A computer-implemented method for generating a color 3D model for a dental restoration. The method receives color information, a color distribution map. and shape for a tooth. The color information is assigned to the color distribution map. The color information and the color distribution map are then combined with the shape to generate a digital color 3D model. The resulting 3D model includes volumes for different color materials for the restoration to provide for color transition zones, which can be 3D printed from the 3D model to made a corresponding restoration.

A dental color key having at least two different color patterns or samples with different tooth colors. The entire surface area of the color key (10) may be smaller than the buccal and/or labial surface area, that is to say the vestibular surface area of two teeth, and the color patterns or samples (12) are attached adjacent to one another and particularly mounted to one single tooth.

A method for monitoring the patient's teeth positioning, including the following steps: a) less than three months after the start of an orthodontic treatment, producing an initial reference model of the patient's arches, and, for each tooth, defining, from initial reference model, a tooth model; b) acquiring at least one updated image of the arches, under actual acquisition conditions; c) analyzing each updated image and producing an updated map relative to a piece of discriminating information; d) optionally determining rough virtual acquisition conditions that approximate the actual acquisition conditions; e) searching each updated image for a final reference model corresponding to the teeth's position during the updated image's acquisition, and; f) for each tooth model, comparing the tooth model's positions in the initial reference model and in reference model obtained at the end of the preceding steps, in order to determine movement of the teeth between steps a) and b).

A disk manager (100) for managing dental blanks (101-1, . . . , 101-n), comprising several receiving compartments (103-1, . . . , 103-n) for receiving one dental blank (101-1, . . . , 101-n) each; and a display device (105-1, . . . , 105-n) for displaying the receiving compartment (103-1, . . . , 103-n) in which a dental blank (101-1, . . . , 101-n) is received.

A method for monitoring a property of the appearance of the teeth of a patient, said method including: A) acquiring, by means of a first acquisition apparatus, at least one first two-dimensional image of said teeth and of a first reference gauge, referred to as initial image; B) acquiring, by means of a second acquisition apparatus, at least one second two-dimensional image of said teeth and of a second reference gauge having the same appearance as the first reference gauge, referred to as updated image; C) standardising the initial and updated images such that the representations of the first and second reference gauges on the standardised initial and updated images have the same appearance; D) before or after step C, marking the same region of the teeth on the initial and updated images; and E) comparing the appearance of said region in the standardised initial and updated images.

An acquisition kit, including: a mouthpiece intended for being placed into the mouth of a patient and including a reference mark; and an image-acquisition apparatus including a screen for viewing an image that can be acquired, computer memory containing information on target acquisition conditions, and a computer program comprising program code instructions for displaying on said screen a reference in a position such that, when the reference mark matches the reference on the screen, the acquisition apparatus complies with the target acquisition conditions.

The invention relates to a glazing composition suitable for glazing the surface a dental zirconia article. The glazing composition comprises a liquid, glass particles, and hydrophilic silica nano-particles. The invention also relates to a process for sintering a porous dental zirconia article with a glazing composition on its surface.
